Sensibility

This makes sense. Therefore, it must be sensible, much like the famous science fellow Albert Einstein. He was rather clever, don't you know? For example, he invented relative physics and some other stuff I'm too stupid to understand.

Sensibility follows Sense, a concept named after two elephants at Knowsley Safari Park when keepers noticed that one (Sense) always followed the other (Sensibility), giving rise to popular novel Sense and Sensibility.
